Another problem with over-water depressurization-
Jet engines gain efficiency with altitude. They are notoriously thirsty at low altitude. If they had to make a decent to 10,000 feet over open water, they would not have enough fuel to reach land.
There are a few corporate jets based at my local airport. They try to coordinate with the tower that once they begin to taxi, they are able to continue directly onto the runway, and take off without stopping. Sitting on the taxiway, an idling jet engine is using similar fuel flow as high-altitude cruise speed.
When on the ground in my little airplane, I always let the jets go first. If I tell the tower guys that I will hold for the jet, the jet's crew always says thanks.
